Question: I am 56 years old and quite pleased with my Ultherapy results from a year ago. How does Infini compare to Ulthera for a sagging neck?
Answer: Infini uniquely differs from Ultherapy which, until now, has been considered a gold standard for non-surgical face and neck lifting. Ulthera is an ultrasound which generates heat to stimulate collagen at two fixed tissue depths, 3 mm and 4.5 mm. Compared to prior devices that didn’t go as deep, Ulthera was based on the premise that deeper penetration may cause more lifting.
Infini is a radio-frequency device which, like Ulthera, also stimulates collagen. Unlike Ultherapy, Infini has numerous tiny micro-needles that can be inserted at different tissue depths. This customizable micro-needle technology combined with variable power settings enables more precise tissue targeting, with the possibility of a stronger collagen response.
Tissue thicknesses vary between the neck, upper and lower face, forehead, lip area and eyelid skin. Infini treatments, with settings customized to area-specific thicknesses in the face or neck, may further improve results. Also, skin collagen differs from that of deeper muscle and fat which Ulthera sometimes penetrates to. Infini-customized treatments that focus on full thickness skin, rather than deeper tissues, may enhance collagen stimulation and tissue tightening.
As an example, a particular patient measures 2.6 mm thick in the lower face (jowl) and 3.5 mm in the neck. While the neck falls within the 3 to 4.5 mm Ultherapy treatment range, Ulthera may go too deep for an effective response in the less deep jowl, which is only 2.6 mm.
Careful consultation with a qualified Facial Plastic Surgeon who has a thorough knowledge of facial anatomy and can customize your treatment using the most suitable “lifting” devices is the first step.
